This project releases GeoIP files automatically every Thursday for routing purpose in Project V. It also provides a command line interface(CLI) tool for users to customize their own GeoIP files.

For all GeoIP files released by this project, see the release branch. Below are download URLs for some GeoIP files:

These two concepts are notable: input and output. The input is the data source and its input format, whereas the output is the destination of the converted data and its output format. What the CLI does is to aggregate all input format data, then convert them to output format and write them to GeoIP files by using the options in the config file.

Supported input formats:

• cutter: Remove data from previous steps
• maxmindGeoLite2CountryCSV: Convert MaxMind GeoLite2 country CSV data to other formats
• maxmindMMDB: Convert MaxMind country mmdb database to other formats
• private: Convert LAN and private network CIDR to other formats
• text: Convert plaintext IP and CIDR to other formats
• v2rayGeoIPDat: Convert V2Ray GeoIP dat to other formats

Supported output formats:

• text: Convert data to plaintext CIDR format
• v2rayGeoIPDat: Convert data to V2Ray GeoIP dat format

1. Install golang and git
2. Clone project code: git clone https://github.com/v2fly/geoip.git
3. Navigate to project root directory: cd geoip
4. Install project dependencies: go mod download
5. Edit config file config.json by referencing the configuration options in configuration.md
6. Generate files: go run ./

• If input format maxmindGeoLite2CountryCSV is specified in config file, you must first download GeoLite2-Country-CSV.zip from MaxMind, then unzip it to geolite2 directory.
• go run ./ will use config.json in current directory as the default config file, or use go run ./ -c /path/to/your/own/config/file.json to specify your own config file.
• The generated files are located at output directory by default.
• Run go run ./ -h for more usage information.
• See configuration.md for all configuration options.

You can run go install -v github.com/v2fly/geoip@latest to install the CLI tool directly.

$ ./geoip -h
Usage of ./geoip:
  -c string
    	Path to the config file (default "config.json")
  -l	List all available input and output formats

$ ./geoip -c config.json
